Energy Tip
of the Day!

Energy star rated compact fluorescent Lamp (CFL) should be the choice in household lighting applications From the extraordinary Gazette notification No. 1611/10 of July 22,2099, the display of the Energy Label  on every CFL was made mandatory. The energy label consists of star rating which varies from  1 star   to 5star higher the number of the star greater the energy efficiency of the CFL. Accordingly CFLs having an energy label with 5 star are  most energy efficient compared to the  CFLs having 1star to  4star rating. By repacking a 1star CFL with 5star CFL with 5-7 watts lower in wattage the same light out put can be gained. Purchasing a CFL with 5 star rating about 5-7 watts  can be cut down At present LED Lamp technology has improved rapidly end in parallel the price of LED lamps have come down to  an affordable Scale for the domestic consumer. Sri Lanka has already introduced performance stety and Minimum Energy performance  standers (MEPS) for LED Lamps introduce for which satisfy MEPS.

Industries

Industry is the production of a good or service within an economy. Manufacturing industry became a key sector of production and labour in European and North American countries during the Industrial Revolution, upsetting previous mercantile and feudal economies. This occurred through many successive rapid advances in technology, such as the production of steel and coal.

Following the Industrial Revolution, perhaps a third of the world's economic output is derived from manufacturing industries. Many developed countries and many developing/semi-developed countries (People's Republic of China, India etc.) depend significantly on manufacturing industry. Industries, the countries they reside in, and the economies of those countries are interlinked in a complex web of interdependence.

The industrial revolution led to the development of factories for large-scale production; with consequent changes in society. Originally the factories were steam-powered, but later transitioned to electricity once an electrical grid was developed. The mechanised assembly line was introduced to assemble parts in a repeatable fashion, with individual workers performing specific steps during the process. This led to significant increases in efficiency, lowering the cost of the end process. Later automation was increasingly used to replace human operators. This process has accelerated with the development of the computer and the robot.

Industry is the one of the largest energy consumers, considering the other sectors like commercial and domestic sectors. Main energy sources used by industries are; electricity, petroleum fuel oils, coal, gases etc.

Followings describe about the high energy consuming sectors and energy conservation opportunities in them. Thermal storage systems and Tri-generation are some advance technological concepts utilised to capture the waste heat or use the low cost energy at off peak time, and consequently improve the efficiency paving the way for energy conservation.
